Rebuild the workspace home as a Windows 8 Start-screen-style tile grid,
replacing the max-w-3xl vertical card list.
Pure core (zero DOM/Svelte/fetch, fully unit-tested):
- logic/tile-layout.ts — geometryFor(width, height) resolves WIDE (4 fixed
~120px rows, column-wise flow, 4x2 span cap) or TALL (2 fixed columns,
row-wise flow, 2x2 cap); pack() is the ONLY order->coordinates transform
(greedy first-fit in fill order, hole-free, render-clamped per geometry);
firstEmptySlot/insertAtFirstEmptySlot/mergeLayout/resizeTile/moveTile/
sortByRecentActivity/sanitizeLayout. Persisted data is
orientation-independent {version:1, tiles:[{id,colSpan,rowSpan,order}]} —
order + spans only, never positions; the same data renders in either
geometry (spans clamp for the render, persisted values untouched).
- logic/drag-controller.ts — pure pointer/press state machine: mouse
threshold-drag + tap-open; touch long-press lifts + selects, pre-lift
movement cancels so vertical scrolling never fights the gesture.
Shell:
- tile-layout-store.svelte.ts — thin reactive wrapper persisting through
the injected createLocalStore adapter (dispatch.workspaces.tiles), ops:
sync/resize/move/placeFirstEmpty/sortByRecentActivity.
- ui/HomeTileGrid.svelte — CSS-grid tile canvas (wide: horizontal scroll +
snap + wheel pan + pan arrow + scroll indicator; tall: native vertical
scroll), FLIP-animated reflow, drag ghost, transient resize preview.
- ui/HomeHeader.svelte — fixed chrome: Dispatch display title, New
workspace popover (same slug validation; creates via create-on-miss and
does NOT navigate — the new tile lands in the first empty slot in fill
order and enters rename mode), global Plugins button, sort-by-recent
overflow; compact icon buttons + bottom sheet on tall screens.
- ui/WorkspaceTile.svelte — tile face (title, /slug, conversation count,
relative last-activity, live active dots, starred tint); inline rename
with the old card's semantics.
- ui/TileActionBar.svelte — slides up on select (right-click / long-press):
Open, Rename, Resize, Star/Unstar, Details, Plugins, Delete (old confirm
+ store call preserved).
- ui/ResizePicker.svelte — Word-style insert-table hover grid (wide 4x2 /
tall 2x2) with arrow/Enter/Escape support and ghost preview on commit.
- ui/WorkspaceDetails.svelte — flyout holding the old card's default-cwd
input + default-computer select (same store calls + error states).
- WorkspacesHome.svelte orchestrates; App.svelte untouched (same props).
- WorkspaceCard.svelte is removed (replaced by the tile system).
Manual tile order rules; starred workspaces get a tint (star is no longer
a sort key); workspaces unknown to the layout append at the end.
vitest: jsdom gains PointerEvent (MouseEvent-based) + Element.animate
stubs — the pointer logic is the outermost edge for the drag tests.
Verification: svelte-check 0/0, vitest 1655 passed (102 files, twice),
biome clean, vite build OK.

Implement the frontend of the Named Agents feature (plan §5-§9):
- New features/named-agents module: pure logic (types re-exported from
@dispatch/wire + transport-contract, validation, provider/model options,
snapshot helpers, network normalizers, auto-save status model) + an injected
auto-save controller (name debounce, immediate provider/model save, monotonic
stale-response guard) + the collapsible sidebar card view.
- Store: /named-agents CRUD + boot seed; selectModel(model, snapshot?) persists
the raw model WITH the namedAgent snapshot; draft promotion carries it;
refreshModel restores ModelResponse.namedAgent.
- Chat store setNamedAgent (sends namedAgent on chat.send); Tab.snapshot +
setSnapshot (retained across rename/remove, persisted with tabs).
- Model selector: synthetic Named Agents provider ALWAYS first; selecting one
resolves to the raw model + records a snapshot; a retained snapshot of a
renamed/removed agent still displays as unavailable (plan §7).
- Composition root wires the view (viewKinds + loaded-modules manifest) + feeds
the selector.
Tests: logic + controller + selector + app-store CRUD (1246 pass), typecheck 0,
biome clean (only pre-existing config infos pending a future migrate), build OK.

Backend (feature/workspace-star) shipped Workspace.starred: boolean (additive
to [email protected], no version bump) + PUT/DELETE /workspaces/:id/star endpoints
(no body; create-on-miss; return the updated Workspace). A starred workspace's
agents jump ahead of non-starred ones in the concurrency limiter queue
(oldest-agent-first within each group); takes effect immediately for
already-queued agents.
FE consumed:
- adapter/http.ts: star(id)/unstar(id) -> WorkspaceResult<Workspace>
(PUT/DELETE /workspaces/:id/star, no body).
- logic/view-model.ts: pure sortWorkspaces (starred-first, then lastActivityAt
desc, stable) + pure applyStarred (the optimistic apply/revert transform).
- store.svelte.ts: setStarred(id, starred) — optimistic flip with error revert;
the list is now a $derived sorted view (starred bubble to top reactively);
no full refresh on success (avoids flicker).
- ui/WorkspaceCard.svelte: star toggle button (filled gold when starred,
outline when not; spinner in flight; aria-pressed/aria-label; tooltip notes
concurrency priority).
- Re-mirrored .dispatch/wire.reference.md (starred + delta note).
- GLOSSARY.md: 'starred' term.
Tests (+27): http star/unstar (5), view-model sort+applyStarred (12), store
optimistic+revert+re-sort (6), WorkspaceCard star button (4).
Verification: typecheck 0/0, 1045 tests green, biome clean, build OK.
backend-handoff.md updated (workspace-star slice, no open backend asks).

Images are now stored on disk under tmp (not SQLite) and served via
GET /images/:conversationId/:imageId. Persisted ImageChunk.url is a compact
relative HTTP path (/images/<conv>/<uuid>.png) instead of a base64 data URL.
No wire/transport-contract type change (behavior only) — re-mirrored the
delta notes.
- New pure resolveImageUrl(url, apiBase) helper (core/chunks/image-url.ts,
+8 tests): data/absolute URLs pass through; relative paths are prepended
with the API base (no double slash; empty base -> root-relative). Exported
from core/chunks + re-exported from features/chat.
- ChatView: new apiBaseUrl prop; <img src> uses resolveImageUrl. The
optimistic echo's data URL passes through; persisted relative paths
resolve against the base. +3 tests.
- AppStore exposes httpBase (getter); App.svelte passes apiBaseUrl into
ChatView and the heartbeat RunModal (also renders image chunks).
Verification: svelte-check 0/0; vitest 959/959 (run twice, +11); biome
clean; vite build OK. See backend-handoff.md §2j-update-2.

Backend vision update (additive to [email protected] / [email protected],
no version bump).
Contracts mirrored (.dispatch/transport-contract.reference.md):
- VisionSettingsResponse + SetVisionSettingsRequest (GET/PUT /settings/vision).
- Delta note: read_image -> consult_vision; numbered placeholders; compaction.
Tool rendering (ChatView):
- read_image test -> consult_vision (rendering is generic by toolName).
- +2 tests: numbered-placeholder text chunk + [Compacted image] text chunk
(both regular text chunks, render as-is — no special handling).
New vision feature library (src/features/vision/):
- logic/view-model.ts (32 tests): VisionSettings/VisionSettingsPatch types
(consumer-defines-port), LoadVisionSettings/SaveVisionSettings ports +
results, normalizeVisionSettings (network-seam coercion), parseImageLimit/
imageLimitChanged, compactionModelOptions (vision-capable models via chat's
public isVisionModel + Auto sentinel), round-trip helpers, imageLimitLabel.
- ui/VisionSettingsView.svelte (9 tests): imageLimit input + Save,
compactionModel dropdown (Auto + vision-capable models), load-on-mount,
save-on-change, error/saved feedback.
- index.ts.
Cross-unit seam: isVisionModel added to features/chat public index.ts
(additive); imported through the public surface, not internals.
Store wiring (src/app/store.svelte.ts):
- visionSettings state + refreshVisionSettings (GET /settings/vision,
normalized at the seam) + setVisionSettings (PUT, partial, returns merged) +
VisionSettingsResult; seeded on boot; exposed on AppStore. +4 store tests.
Mounted in App.svelte: new "Vision" sidebar view kind + VisionSettingsView
in viewContent (not conversation-scoped); load/save adapters; visionManifest.
Verification: svelte-check 0/0; vitest 948/948 (run twice, +47 since the
prior vision commit); biome clean; vite build OK. See backend-handoff.md §2j.

Vision & vision-handoff frontend (consumes the backend's additive
[email protected] / [email protected] image types — no version bump).
Contracts mirrored:
- .dispatch/wire.reference.md: ImageChunk added to the Chunk union +
ImageChunk/ImageInput interfaces.
- .dispatch/transport-contract.reference.md: ChatRequest.images,
ModelMetadata.vision, + ImageChunk/ImageInput re-exports.
Core (core/chunks):
- conformance: assertChunkExhaustive handles the new 'image' variant
(the guard caught it — its purpose).
- appendUserMessage(state, text, images?) echoes a [text, image, ...]
user run; the user-message event dedup scans the trailing user run
(not just the last chunk) so an image-bearing echo doesn't duplicate
the text; applyHistory's during-gen dedup matches a multi-chunk echo
by content equality (chunkContentEquals + trailingRun helpers).
UI:
- ChatView renders user 'image' chunks as lazy <img> bubbles; a
non-vision model's persisted [image, analysis-text] both render.
read_image tool renders generically (no special-casing).
- Composer: clipboard paste / file picker / drag-drop of images ->
base64 data URLs, thumbnail previews with remove, forwarded on
chat.send (omitted when none). Image-only sends allowed; steering
(chat.queue) never forwards images.
- ModelSelector: vision badge (isVisionModel) marks vision-capable
models; indicator shows native-vision vs vision-handoff hint.
Store wiring: ChatStore.send + AppStore.send + App.svelte handleSend
thread images through; chat.send still omits cwd (only images added).
Verification: svelte-check 0/0; vitest 901/901 (run twice, +34 new);
biome clean; vite build OK. See backend-handoff.md §2j.

Mirrors the cwd/workspace UI for the SSH-computer feature:
- New feature library src/features/computer/:
- logic/view-model.ts (pure): viewComputer/viewComputerStatus/viewTestResult/
summarizeComputers/formatHost/knownHostLabel + state->badge for the 4
ComputerStatusResponse states + SaveComputer/LoadComputerStatus/
TestComputer/LoadComputers ports. 20 view-model tests.
- ui/ComputerField.svelte: per-conversation selector (dropdown +
connection-status badge + Test-connection, polling the selected alias).
- ui/ComputerSelect.svelte: reusable Local/computers dropdown, shared with
the workspace default-computer control.
- AppStore: computerId state + refreshComputer (at every focus site, parallel
to refreshCwd) + setComputer (PUT /conversations/:id/computer, null=clear) +
global computers catalog (GET /computers on boot, like models) +
computerStatus(alias) + testComputer(alias). chat.send UNCHANGED (resolved
server-side like cwd).
- App.svelte: ComputerField in the Model sidebar view next to CwdField; adapted
ports wrap the store.
- workspaces: setDefaultComputer on WorkspaceHttp+WorkspaceStore
(PUT /workspaces/:id/default-computer); default-computer selector in
WorkspaceCard (reuses ComputerSelect); router passes store.computers through.
- Re-mirrored .dispatch/transport-contract.reference.md (Computers section +
ChatRequest.computerId); updated .dispatch/wire.reference.md (Computer/
ComputerEntry/defaultComputerId + the provider-retry divergence note from
handoff #1); GLOSSARY + backend-handoff.md (handoff #2, §2e).
Transparency invariant: the computer is USER-facing only (a tool-execution
target, never part of the model prompt); the agent never sees it.
Verify: 795/795 tests green; biome clean; vite build succeeds; 0 typecheck
errors from the computer feature. (11 pre-existing svelte-check errors remain
from the open §2d provider-retry divergence — backend feature/ssh-support
still lacks TurnProviderRetryEvent; not from this feature.)

boundaries
Consume the message-queue + steering handoff ([email protected], [email protected]).
Re-pinned file: deps + re-mirrored .dispatch/*.reference.md.
- fold steering AgentEvent into the transcript as a provisional user bubble
(after the tool-result it followed; no de-dup — the queue surface carried it)
- add rendererId: "message-queue" custom renderer (pure parser + MessageQueueList)
rendered as a compact panel above the Composer (hidden when queue is empty)
- add ChatStore.queueMessage / AppStore.queueMessage — sends chat.queue WS op
(trim/validate non-empty; auto-starts a turn if idle)
- Composer switches to chat.queue while generating (button → Queue, placeholder
→ Steer the conversation...)
- exhaustiveness guards updated for steering + chat.queue
- carry-to-new-turn needs no special handling (normal new turn)
664 tests green.

thinking-depth knob
Consume the backend's reasoning-effort handoff ([email protected] ReasoningEffort +
[email protected] GET/PUT /conversations/:id/reasoning-effort,
ChatRequest.reasoningEffort): a 5-level selector in the sidebar Model view,
under the provider + model dropdowns. null renders as 'high (default)' per
the server-owned resolution chain; PUT on change (effective next turn);
error + revert on 400; per-conversation re-mount incl. drafts (the draft id
survives promotion, so an effort set on a draft applies from turn 1).
Re-mirrored .dispatch references; GLOSSARY 'reasoning effort'; handoff
updated. 616 tests green; live curl probe passed.

show-earlier backfill
Re-pinned [email protected]>0.10.0 + [email protected]>0.6.1 (reply
frontend-history-windowing-handoff.md); re-mirrored both .dispatch references.
- HistorySync port gains optional { limit?, beforeSeq? } (CR-5 params); the
app's createHistorySync appends them to GET /conversations/:id.
- COLD-cache fresh load now fetches ?sinceSeq=0&limit=<floor(0.75xL)> — a huge
conversation no longer ships whole to show 192 chunks. A warm-cache tail sync
stays unwindowed (windowing a tail that outgrew the limit would leave a
silent seq gap behind the cache).
- hasEarlier now derives from the [email protected] CONTRACT (1-based gap-free seqs):
loaded window starting above seq 1 => older history exists — covering both
locally-trimmed AND server-windowed transcripts (the watermark stays as the
merge floor only).
- showEarlier(): local cache first; when the cache doesn't reach far enough
back, backfills the missing older run via ?beforeSeq=<oldestKnown>&limit=
and persists it (next page-in is local). latestSeq windowed-read caveat is
satisfied structurally (tail cursor derives from the cache's max seq).
- live-probe: +6 CR-5 checks (seq origin, newest-k ascending, short-chat
exactness, beforeSeq paging, 400 validation x2). NOT yet run live — backend
was down at commit time; run pending.
- backend-handoff.md: CR-5 RESOLVED, pins/mirrors current. 602 tests green x2.

show-earlier page-in
Long transcripts no longer grow unbounded: past the chat limit (default 256
chunks, localStorage dispatch.chatLimit) the oldest ceil(limit/4) committed
chunks are unloaded in ONE bulk pass — never one-per-delta (old Dispatch's
scroll-jump-per-step bug) — and only while the reader is stuck to the bottom
(scrolled-up readers defer the trim; it catches up in whole quarters). A fresh
page load windows to the newest floor(0.75*limit). Unloading is purely local
(IndexedDB cache + server keep everything); a hiddenBeforeSeq watermark keeps
history merges from resurrecting unloaded chunks, and a 'Show earlier messages'
affordance pages a quarter back in from the cache with scroll-anchor
preservation. Thinking-collapse render keys stay stable across trims via a
hiddenThinkingCount ordinal base.
- core/chunks/trim.ts: pure policy (trim/window/restore/normalize) + tests
- chat store: chatLimit + canUnload deps, windowed load, showEarlier()
- composition root: dispatch.chatLimit localStorage knob + unload gate wired
to smart-scroll isAtBottom()
- backend CR-5 OPENED (not a blocker): ?limit=/?beforeSeq= on
GET /conversations/:id (courier backend-handoff-chat-limit.md)
- scripts/live-probe.ts: fix pre-existing stale TurnMetricsEntry reads
(m1.usage -> total.usage) that crashed the probe; 17/17 live checks pass

Restore the ergonomic composer from old Dispatch: an auto-resizing textarea
(1→7 lines) with a fixed-width Send button beside it, and a status bar BELOW
holding a status icon · context-window fill bar (escalating success/warning/
error color) · compact token count (current / limit · pct%).
The bar reuses the latest turn's contextSize as current usage and HARDCODES a
1,000,000-token window limit as a placeholder (real per-model limit is the next
backend ask). Absorbs the standalone ContextSizeBadge (removed). Pure helpers
computeContextUsage + formatCompactTokens added to core/metrics (tested).
540 tests green.
|
|
Backend context-size handoff: re-pin [email protected] / [email protected]
(+ re-mirror .dispatch reference snapshots). Thread the optional contextSize
through core/metrics (done fold + durable + selectCurrentContextSize: latest
turn's defined value, undefined=>unknown never 0, durable-wins-over-live).
Chat store exposes currentContextSize; ContextSizeBadge renders
"N tokens in context" / "context size unknown" above the composer.
GLOSSARY: add context size / context window. 533 tests green.
|
|
Consume [email protected] / [email protected] metrics: usage.stepId,
step-complete (ttft/decode/genTotal), done.durationMs/usage, and the
durable GET /conversations/:id/metrics endpoint.
- core/metrics: pure live-fold + durable-merge reducer; decode-rate TPS;
head-aligned, stable placement; progressive per-step rows (each shown as
its step ends) with the turn-total row gated on the done event.
- features/chat: store folds metric events + hydrates durable TurnMetrics;
ChatView renders inline step bubbles + a turn-total bubble.
- app: MetricsSync HTTP effect (tolerates 404) injected into chat stores.
- scripts/live-probe: drives the metrics path; live-verified 17/17 vs bin/up.
- docs: regenerate .dispatch wire/transport mirrors to 0.4.0; glossary terms
(turn/step metrics, TTFT, decode time, TPS, metrics bubble); trim handoff.
